there must be an issue, because all that is not true.

+ you can use it with bluewallet - we worked hard to make it possible to continue to use BlueWallet also with the self-sovereign Alby Hub and any NWC based wallet

+ what means "it cannot be used with qr" ? you can not scan a QR code which QR code - with which wallet?

+ there is a free reserve (like any wallet does it) sadly this is because it is still hard/impossible to know the exact ln fees before the payment. if you want to close the account you can drain it in a few steps and we also send the last sat to you.

so it seems you have some misunderstanding and issue that we're happy to help solving.
